Before installation
Confirm the exact Galaxy model and regional variant support eSIM. Open Settings and look for Connections, SIM Manager, and Add eSIM. The phone must also be carrier-unlocked. Save the QR code, manual activation details, and provider support information.
Install through SIM Manager
Open Settings, Connections, SIM Manager, then Add eSIM. Choose the QR-code option or the provider-supported installation method. Scan the code and allow the phone to download the profile over Wi-Fi. Menu names can vary by One UI version and carrier software.
Name and organize the lines
Give the new profile a clear travel label. Keep the US SIM identifiable so calls and texts do not accidentally use the wrong line. Samsung models can offer preferred SIM settings for calls, messages, and mobile data.
Set mobile data
Choose the travel eSIM for mobile data when the plan is ready. Follow the provider's data-roaming guidance for that line. Review automatic data switching because the home SIM could use roaming data if switching is permitted and the travel line loses service.
Troubleshoot without deleting
Restart the phone, confirm the eSIM is enabled, check mobile data and roaming, review APN instructions, and try the supported local network. Do not delete the profile unless provider support confirms that the QR code can be reused or a replacement can be issued.
